Ordering number : ENN4943A Monolithic Digital IC LB1863M, 1869M Two-Phase Unipolar Brushless Motor Driver Automatic Recovery Type Circuit in a Miniature Flat Package Overview Package Dimensions The LB1863M and LB1869M are 2-phase unipolar unit: mm brushless motor drivers that are provided in a miniature 3111-MFP14S flat package that contributes to end product LB1863M, 1869M miniaturization and supports automatic mounting. These products support the implementation of motor drive lock 8 14 protection and automatic recovery circuits, and alarm specifications with a minimal number of external components. Features and Functions Hall elements can be connected directly to the IC itself. 1 7 0.15 1.5-A output current output transistors built in 8.0 Rotation detection function that provides a low-level output during motor drive and a high-level output when the motor is stopped 0.35 1.0 1.0 Motor lock protection and automatic recovery functions SANYO: MFP14S built in Thermal shutdown circuit Switching noise can be reduced with an external ceramic capacitor. Classification Package MFP-14S System voltage 12 V LB1869M 24 V LB1863M Note: The LB1869M and LB1863M are pin compatible so that the same printed circuit board can be used for both 12 V and 24 V products. Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircrafts control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
